2, when the operation gear-change hand lever, when making declutch shift shaft I53 pull out gearbox body 9, shift fork I47 moves with declutch shift shaft I53 by elastic cylindrical pin 50 and spring cotter 49, thereby drives variable gear I39 and gear IX31 engagement.At this moment, the engine power drive path is: pass miniature gears 15 → differential assembly 10 driving engine → belt → clutch assembly 37 → input shaft 38 → variable gear I39 → gear IX31 → I axle 30 → gear VIII28 → gear V22 → tween drive shaft 25 → gear VI24 → gear IV17 → end, rotate by semiaxis, wheel hub drive wheels then, make the vehicle forward travel.
3, when the operation gear-change hand lever, when making declutch shift shaft II54 push gearbox body 9, shift fork II48 moves with declutch shift shaft II54 by elastic cylindrical pin 50 and spring cotter 49, thereby drives variable gear II40 slippage and gear V22 engagement.At this moment, the engine power drive path is: pass miniature gears 15 → differential assembly 10 driving engine → belt → clutch assembly 37 → input shaft 38 → variable gear II40 → gear V22 → tween drive shaft 25 → gear VI24 → gear IV17 → output shaft 20 → end, rotate by semiaxis, wheel hub drive wheels then, vehicle is swung to travel.
4, when handling gear-change hand lever, when making declutch shift shaft II54 pull out gearbox body 9, declutch shift shaft II54 drives shift fork II48 by elastic cylindrical pin 50 and spring cotter 49 and moves together, thereby drives variable gear II40 and gear VII26 engagement.At this moment, the engine power drive path is: pass miniature gears 15 → differential assembly 10 driving engine → belt → clutch assembly 37 → input shaft 38 → variable gear II40 → gear VII26 → I axle 30 → gear VIII28 → gear V22 → tween drive shaft 25 → gear VI24 → gear IV17 → output shaft 20 → end, rotate by semiaxis, wheel hub drive wheels then, make the vehicle forward travel.
5, when the operation gear-change hand lever, when making declutch shift shaft III52 push gearbox body 9, declutch shift shaft III52 drives shift fork III51 by elastic cylindrical pin 50 and spring cotter 49 and moves together, thereby drives duplex variable gear 41 and gear II13 engagement.At this moment, the engine power drive path is: pass miniature gears 15 → differential assembly 10 driving engine → belt → clutch assembly 37 → input shaft 38 → duplex variable gear 41 → gear II13 → output shaft 20 → end, rotate by semiaxis, wheel hub drive wheels then, make the vehicle forward travel.
6, when the operation gear-change hand lever, when making declutch shift shaft III52 pull out gearbox body 9, declutch shift shaft III52 drives shift fork III51 by elastic cylindrical pin 50 and spring cotter 49 and moves together, thereby drives duplex variable gear 41 and gear I11 engagement.At this moment, the engine power drive path is: pass miniature gears 15 → differential assembly 10 driving engine → belt → clutch assembly 37 → input shaft 38 → duplex variable gear 41 → gear I11 → output shaft 20 → end, rotate by semiaxis, wheel hub drive wheels then, make the vehicle forward travel.
Said " connected rear axle " means: be to be connected as a single entity by fastener between gearbox body and the rear axle housing body, engine power passes on the change speed gear box input shaft behind the clutch pulley through belt, directly pass on the semiaxis through change speed gear box inner gear and differential assembly, such change speed gear box and back axle are generically and collectively referred to as " connected rear axle " again.
Good effect of the present utility model:
The utility model has only increased a gear and an axle on 4+1 gearbox basis, real Having showed increases a forward gear, and it is more rational that speed is distributed, and has guaranteed that vehicle do not going the same way Use suitable travel speed under the condition, thereby greatly improved serviceability and the economic performance of vehicle.
